Description

Substantial progress has been made recently in the generation of master-field ensembles.
This has to be paired with efficient techniques to compute observables on gauge field configurations with a large volume.
Here we present the results of the computation of hadronic observables, including hadron masses and meson decay constants, on large-volume and master-field ensembles with physical volumes of up to $(18\,\mathrm{fm})^4$ and $m_\pi L$ up to 25, simulated using $N_{\mathrm{f}}=2+1$ stabilized Wilson fermions.
We obtain sub-percent determinations from single gauge configurations with the combined use of position-space techniques, volume averages and master-field error estimation.
